About this fungus

Gemina Honey Mushroom is a fungus in the Physalacriaceae family. Its habitat and field characteristics are summarised below.

A clustered honey fungus with yellow-brown caps, pale gills and usually a stem ring.

What to check

Look for growth from wood or buried roots, a white spore print, fibrous cap scales and black root-like rhizomorphs nearby.

Variation

Cap colour, scales and ring development vary with age and weather.

Lookalikes

Other Armillaria overlap almost completely in the field. Pholiota and Galerina differ in spore colour but include poisonous species.

Habitat and range

Recorded mainly in northeastern North America, where it can act as a root pathogen and wood decomposer.

Food safety

Edibility is uncertain or disputed.
